This work elucidates the electronic structure, electron field emission and magnetic behaviors of carbon nanotube (CNT) fabricated without catalyst by the dip deposition method on the La0.66Sr0.33MnO3 (LSMO) as base layer. X-ray absorption near edge spectroscopy (XANES), valence band spectroscopy (VBPES) and Raman spectroscopy were used for the study of electronic properties; whereas the magnetization (M) was measured versus applied magnetic field strength (H), using a commercial physics properties measurement system (PPMS) at a temperatures range between 5 K and 305 K. In addition the electron field emission characteristics were performed using the instrument Keithley Model 237 with a power supply.
